--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note it is created in the caller context, thus

double foo(double *, double *, int)
__attribute__((target_clones("avx,default")));

double x;
int main()
{
  double a,b;
  x = foo (&a, &b, 1);
}

creates it in the program.  I suppose that's a feature (but it will complicate
handling in libgfortran as you need to "register" the proper target-clones
in the FE when compiling user code so the resolvers get created there).
